Hello! I have a problem with working in the Curves in Lightroom. I can not move the points on the curve with the mouse and pen tablet. I click the mouse on the point, but the point is not moving as though I had not pinched. Or point move, but returns to its original position.

Tried to change the mouse - the problem persists

is it possible that this is due to go on mac os Sierra

perhaps you have the same problem. is there a solution to this problem?

I posted what I thought was a different bug, but upon rereading this thread, I am pretty sure that we are talking about the same thing. I am going to roll back to an earlier version of Lightroom in order to continue. (Thanks, Victoria, for linking to that post).

Unfortunately I still have terrible interaction with this latest update, using an Apple Magic Mouse, running Mac OS Sierra 10.12.1 (it's so bad it's useless to use, and I need to work with curves all the time, so very unfortunate). Using the Wacom Intous 3, it seems to be better. I had much hoped the bug was fixed when reading the release notes. Seems you still have some way to go. Hope you get it right soon.

@Rikk Flohr: You are mistaken. The problem is definitely not solved in Lightroom 2015.8 and Sierra. Not only is the tone curve STILL extremely difficult to work with, but the color adjust drag tool is just as problematic. As an example, when trying to RAISE saturation the sliders will actually LOWER the saturation! Not only are these problems extremely frustrating but the fact that Adobe has not addressed these issues after months is inexcusable. Please fix this!

Regarding the HSL Target Adjustment Tool. I just tested on Windows 10 and Mac Sierra using the trackpad on both laptops and it is behaving as expected. In Saturation: Click+Drag Up raises the slider. Click+Drag Down lowers the sliders.

I also tested on Mac with a Magic Mouse. In click and drag mode it works as expected and it touch/swipe mode it works as expected.

If you are seeing behavior other than that please provide your Operating System and version, the type of Pointing Device you are using, and its driver version. I would ask that you include a video if possible that show your finger movement. I understand if that is too difficult to record your hand and the screen simultaneously.

Sure, I'll try, Rikk. And thanks for the quick feedback. The issue is that the moving curve points in the freeform mode (not parameters), the movement get's very jerky, to the point of unusable, especially if several points are presents, and accuracy is required. Moving mouse pointer over screen (without adjusting anything), I can move it very smoothly, e.g. along a horisontal line, without trying hard at all. Pulling a curve point around, the movement is all jerky/jumpy, and pulling horizontally, as an example, you notice obvious bumps up and down, for no apparent reason.

Actually it seems the Wacom wasn't much better/normal than originally thought. One observation now though is that having "Use Graphics Processor" on makes the issue much worse. Having it off makes it better, but still very much not smooth at all.

Another observation. When releasing the mouse/pen, I notice the cursor appearing somewhere else than where I let go. Might be a hint at debugging. It could seem mouse accelleration is being somehow countered. At least something is clearly working against the movement you're trying to accomplish.

A side note. Wasn't it possible to drag points outside the curve area to delete them? Seems only context menu can do that now. I liked the dragging outside.

Running a late 2013 13" MacBook Pro Retina. And mostly everything seems slow, with this curves adjustment becoming a real something to operate. As much as I love Lightroom, being a user over many years, the dragging performance is getting harder and harder to bear. I know a newer machine could help somewhat, but feel a lot more could be pulled with current hardware. Perhaps newer versions can make better use of hardware for a more fluent interface. Crossing my fingers, wanting to stay with Lightroom, and wishing it all the best.

If any help I can give more info, technical or descriptive of observed behaviour. You can even try it out yourself, or I can make a recording, although direct, on-the-spot, interaction is best to feel the jurky disconnected feeling and behaviour.

Thanks Rikk for your attention to this matter. I got super excited when I saw your post about the issue being addressed in CC 2015.8. I just wanted to post to say that I'm seeing precisely the same things that Henrik is describing. In disabling GPU Acceleration, things are much more manageable. There is still a slow to respond jerky quality to the movement of control points, but it is at least allowing me to move them in the direction my mouse is moving and I can generally place the point where I want it to go. The frustration with this is magnified when working in Photoshop and I see such a smooth responsive integration of curves that is just not currently present in Lightroom.

@Rikk. Holding shift down, being restricted to vertical moves, I see no jurky sideways jumps. But I don't either without shift. The bumpy road seems to be appear to horizontal movements.

I did just observe something new, focusing on vertical movement. I can get into a situation where point won't move at all, becoming stuck, without significant mouse movement (like many centimeters, almost running out of mouse pad coverage) - after a long movement suddenly point starts moving again.The whole disconnected experience seems to be out of sync with current mouse movement, as if some state accumulates in a bad way, getting worse and worse the more you pull around. E.g. dragging a point vertically, deliberately towards the very bottom (and "past" it), and then up again, it seems you need to "wheel in" the excess drag (and possible more), before the point moves up again. Not like that on horisontal axis.

Regarding Alt, the bumps seem to have less amplitude. But another bug appears (oh my). Pulling a point to the right (with Alt), I can only move it so much, before it stops completely in horizontal movement - like hitting an artificial wall, even though not being anywhere near right side of curve area yet. Perhaps code thinks I'm outside application window, or at it's border and won't take in more movement that way. Confirming the idea that point movement is out of sync with cursor info.

Running on an external 4K monitor (Dell P2715Q) - wonder if that is a particular use case triggering the behaviour. Will try without external screen later.

Really hope for a very quick fix for this. Thought I was being very patient waiting for this new release, but still not having it fixed is a bit of a hard time. Wish you luck.

Tried with external display attached, using only the internal display and built-in trackpad. Still bugged. Can repeat vertical movement issue, running "past" the bottom, and having to "wheel in" overshoot (it's an example, can also get stuck somewhere within curve boundary, but this triggers behaviour repeatedly). Horizontal bug, where moving to the right and getting stuck way before hitting right hand side, is also repeatable, now without needing Alt.The whole thing is terrible as it stands right now. Sorry to see this not being picked up by QA.

When I first downloaded Lightroom 2015.6 I was on El Capitan and everything was OK. But these problems started after installing Sierra. What I don't understand is that Camera Raw CC 9.8 works perfectly.

I created a video showing the problem but I don't belong to any of the video sharing sites. Is there another way of uploading?

As a heavy desktop user, and not mobile, I wish the desktop version could get some more attention/ressources assigned. It seems the mobile line is flying. I wish someone at Adobe would consider more attention to desktop version, where the real serious editing is being done, and not on fancy mobile trending apps (they are nice, but I would _much_ rather have a better working desktop version - at least working, but also better performance wise). Hope the needed attention will come true, and perhaps a more performant architecture can be followed.

Example of bug in Lightroom CC 2015.8 when moving control point in "Custom Control Points". Trying to move control point smoothly from side to side, horizontally, but not possible. Notice straight movement before attempting to drag point. When dragging point, erratic jumpy behaviour starts, so even though actual mouse movement is smooth from side to side as before attempting to drag, the resulting control point movement is bumping up and down. And actually hits an artificial "wall" at the end of the clip, where the point cannot be moved any further to the right, but still vertically.

This is currently best case scenario. Erratic control point movement is significantly worse when having GPU Acceleration On, it's currently Off. And worse when multiple points are used.

Hi everyone. I have reported what is either the same bug, or a related bug, in a different thread. In that thread I have suggested a work-around which I suggest you try, in case that we are talking about the same issue (which I am not sure of). It has also been suggested elsewhere that editing in Lightroom mobile is a work-around. I don't use Lightroom mobile, so I can't comment on this. Adobe has acknowledged my bug report, and I hope it will be fixed in the next release of LR.

Having to check for widespread issue like this one BEFORE installing an update certainly reduces the value of having a subscription to the software. I'm essentially staying one version back all the time because I'm afraid to install an update that breaks something I need to work! :/
